Our script is primitive at best but does seem to do the job okay:
http://pfsense.com/cgi-bin/cvsweb.cgi/pfSense/usr/local/sbin/racoon_watch.sh?rev=1.8;content-type=text%2Fplain

Let me know if it helps.  This generally well detect the problem quick
enough to minimize downtime between the tunnels (in our experience).
